From the AP, Crossroads GPS takes down an ad that Democratic Senate candidate Heidi Heitkamp called false:

The ad claims when Heitkamp was attorney general during the 1990s, she spent taxpayer money on private airplanes.
Heitkamp on Thursday called the statement “completely false” and asked TV stations to quit running it.

It was produced by Crossroads GPS, an organization that supports Republicans. A Crossroads spokesman says the ad has been taken down voluntarily. The group had intended to spend $191,000 running it into the middle of next week.

A manager at one of the stations told me the ad was pulled this morning, saying his understanding is the spot was being "revised" and that there will be new a new spot shipped to replace it. But it's a victory for Democrats against a group that, depending on what decisions are made, could play a major role in Republican efforts to take back the Senate majority.

UPDATE: A Crossroads spokesman insisted this wasn't a reactive move, saying they hadn't received notification from Heidi Heitkamp or North Dakota stations, and that "after we realized a content issue the ad was voluntarily removed from rotation, but the message of the ad remains: Heidi Heitkamp has a long record of supporting tax hikes on North Dakota families and job creators."

UPDATE II: Julie Bernhardt, of station KMXC in North Dakota, said officials with her shop sent word to "the company" behind the ad that there had been complaints from Heitkamp's team well prior to the spot getting pulled.
